The upper ends of the frame being entirely open. Theframe the plates 22 are provided with. lateral which at its lower end4that by providing anges that have inserted therethrough bolts or othersuitable fastening elements 26.

I provide a tank 27 that is secured upon 'the wall 4 and disposed withinthe frame 1. A depending vdischarge pipe 2S is carried by tank 27 and atits lower end is connected with a discharge nozzle 29 that is preferablyformed with a number of perforations so as to emit a tine spray ofliquid. Any number of these nozzles 29 and pipes 28 may be provided. Avalve 30 is carried by the pipe 28 so as to cut otf the supply to thenozzle. Water or a cleaning fluid of any kind may be carried within thetank 27 and it is preferable to arrange the nozzle 29 in the rear of thebrushing members and in alinement therewith. A filling tube or pipe 31is eX- tended upwardly through the top. Wall 4 and the cap 32 isremovably mounted upon said pipe 31.

I provide a handle for guiding or pushing the device designated 33. Thishandle is pivoted as at 35 to the side walls 2 bf the frame 1 and isprovided with a grip portion 35.

Fixed upon the shaft upon which the pinion 11 is mounted is a pulley 36u on which is mounted a belt 37. The belt 3 is also mounted upon thepulley 38 that is carried upon the shaft 39 of a rotary suction pump 40.The pump 40 is carried by the top wall 4 in depending relation theretoat a point rearwardly of the motor 1U. Connected with the pump 40 andextending downwardly toward the floor is a suction pipe 41 is connectedto` and carries an elongated suction pan 42. This pan 42 is ofsuch'length as to cover the area of floor surface operated upon by thescrubbingmembers 17 and is provided for the drying of the door bysucking the moisture upwardly through the pipe 41 to the pump 40. A tank43 iscarried in any suitable manner interiorly of the upon one side wallthereof and a pipe 44 connects the tank 43 with the ump 40. Theinoistureor liquid'sucked or rawn upwardly by the pan 42 and pipe 41 and pump 40is forced' through the pipe 44 into the tank 43 from whencel it may bedrawn by suitable means not shown'. It will be seen a suction pan 42 tocover the expanse of floor which has been scrubbed that a drying of thefloor may be quickly and reliably edected.

In operation, assuming that the motor 10 is operated the shaft 7 isrotated and propels the device. By means of the gears 16 and 16Br thecrank shaft 15 isrrotated and the rods 20 and 21. VThe rods 24 'members17 in .their reciprocal movements so-{that effective and expeditiousscrubbing or polishing action is had. If desired the a reciprocatorymovement to the 16 and 17 through the medium of guide the imp arts vmembers frame 1 preferably brushes 19 may bc removed and polishingelements not shown, placed within the holder 18. The surface beingtreated may be sprayed `with the liquid within the tank 27 and athorough polishing or tion is thus provided. By means of the handle 33the device may be guided in the proper direction and in view of the factthat the rollers 5 are arranged at the four corners of the rectangularframe, the device is supported evenly and in such manner that thebrushes or scrubbing elements will move smoothly and not cause thesurface being treated to become streaked or injured in any manner.

By means of the suction pan 42 and the operating means therefor it willbe seen that the iioor will be dried in an effective manner and that allwet lint and other foreign matter will be removed from the floor. Adrain cock 45 is provided for the tank 43 and extends through one of theside walls of the frame 1 as shown clearly in Fig. 3.

With reference to the foregoing description and accompanying drawings,it will be observed that I have provided a compact and easily operablemachine that will operate in a reliable and effective manner to clean orpolish a wide strip of floor surface in such manner that injury orstreaking of the surface is prevented.

In practice, have found that the form of my invention, illustrated inthe drawings and referred to in the' above description, as the preferredembodiment, is the most eficient and practical; yet realizing that theconditions concurrent with the adoption of my device will necessarilyvary, I desire to emphasizethe fact that various minor changes indetails of construction, proportion, and arrangement of parts may beresorted to, when required, without sacrificing any of the advantages ofmy invention, as set forth.

What is claimed is f @1. A lscrubbing machine including a rectangularframe, rollers carried at the corners of the frame, a shaft journaledtransverlse'ly of the frame,

supporting wheels tate thereon, means to rotate said shaft, a crankshaft carried within'the frame, scrubbing members, rods connecting thecrank shaft with the scrubbing members, means to rotate said -crankshaft, depending 'de plates carried by theA frame, blocks'sli ablevertically within the guide plates and guide rods connecting hescrubbing members with said blocks.

l2. A scrubbing machine including a rectangular frame, rollers carriedat the corners of the frame, a shaft journaled transversely of theframe, mounted upon said-shaft and arranged to rotate thereon, means torotate said shaft, a crank shaft carried within the frame,

supporting wheels scrubbing members, crank shaft with th means to rotatesaid rods connecting the e scribbing members, crank shaft, dependingguide plates carried by the frame,

blocks slidable vertic ally within the guide plates, guide rodsconnecting the scrubbing members with said blocks,

said guide plates being arranged above and rearwardly of the scrubbingmembers, and a guide handle carried b said frame.

In testimony whereof I aflx my signature in presence of two witnesses.
